A new method to decode how DNA 'switches' control gene activity
DNA is the blueprint of life. Genes encode proteins and serve as the body’s basic components. However, building a functioning organism also requires precise instructions about when, where, and how much those components should be produced.

Female meiosis in plants can be directly observed with new method
A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female meiosis—the process by which germ cells are formed—in the model plant Arabidopsis thaliana. The FeM-ID (Female Meiotic cell…

Global study finds smaller fish and shifting food webs despite stable species numbers
Species numbers alone do not fully capture how ecosystems are changing. In a global study, scientists analyzed long-term data from nearly 15,000 marine and freshwater fish communities. They found that fish food webs have changed substantially…

Why do people living at high altitudes have better glucose control? The answer was in plain sight
In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking observations from that work was a dramatic…

Hiding in plain sight: Discovery of cryptic species could double the number of vertebrates
There may be twice as many vertebrates on the planet as previous estimates claimed, according to a new study published in the journal Proceedings of the Royal Society B: Biological Sciences. That’s not because of any errors or miscalculation, but…
